Hello, I'm DVdm. I wanted to let you know that I removed an external link you added to the page Global Positioning System because it seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thanks. DVdm (talk) 12:18, 7 April 2015 (UTC)
